Tanker heating technology

Tank trucks play a very important role in the process of oil and gas storage and transportation. In the storage and transportation of oil and gas, most tankers are used for oil storage and transportation. When oil is needed, the oil is output from the tank. In the process of exporting oil products, such a problem is inevitably encountered. Due to the low temperature, the oil product becomes viscous and the fluidity of the oil product is reduced. As a result, the oil product cannot be smoothly exported from the oil tank. Question, how to solve it? According to the "Tank Heating Technology Promotion Center" introduction, the new local rapid heating technology for oil tanks has solved this problem.

Tank heating

Tank local fast heater
working principle:
1, the "vortex hot film heat exchanger" along the radial extension of the tank into the bottom of the tank, hot medium (steam) take the tube, the oil flow from the shell within the tube, the shell oil inlet directly connected to the tank Internal media.
2. A temperature control valve is set at the steam inlet of the heat exchanger, and the temperature of the oil outlet is detected by the temperature probe to control the steam inlet steam inlet of the heat exchanger so as to ensure the temperature of the oil product is constant.
The heat exchanger adopts the high-efficiency heat exchange element—the eddy current hot film tube, to maintain the reasonable flow of oil products between the tubes. The thermal efficiency is 3-5 times that of ordinary heat exchangers. The heat transfer enhancement mechanism is: the oil fluid flows on the internal and external surfaces. When it is designed as a turbulent flow, it will produce strong vibration and scouring action. The direction of flow will change continuously. The high-temperature oil fluid that keeps close to the surface of the pipe will be continuously replaced, the insulation layer will be thinned and even destroyed, and the heat transfer on the metal surface will be accelerated. The microscopic vortex strengthens the internal heat diffusion of the oil fluid. The local high-temperature overheating of the fluid close to the surface of the pipe wall is not caused, so that the oil product can be properly and sufficiently heated without the possibility of coking and decomposing. Both heat transfer is good, but it will not be very resistant.
Heating features:
1, fast heating, high heat transfer efficiency, easy to scale.
2, can quantitatively heat the oil, how much heating is needed.
3, the oil will not appear local high temperature, carbonization, to ensure the oil quality and heater heat transfer efficiency.
4. The oil outlet temperature in the oil tank is the highest, which ensures the oil flowability.
5. It avoids repeatedly heating the oil in the tank, ensuring the chroma of the oil and reducing the cost of the oil treatment.
6, long service life, corrosion resistance, high temperature, high pressure, anti-fouling function, greatly improving the overall performance of the heat exchanger.
7. The advanced design of the process structure guarantees a smooth outflow of oil products and a better “bottomed” effect.
8, can achieve automatic control, according to the oil inlet and outlet temperature and inverted oil flow control steam feed.
9, compact structure, easy installation and maintenance, will not affect the safety of the tank due to the installation of the heater. Compared with the U-tube heat exchanger, in the case of the same heat exchange area: the size of the eddy current heat film heat exchanger is only about half of the U-tube heat exchanger's external dimensions.
10. Compared with the electric heating method, it is safer, the heating is gentler, and the effect on the oil quality is smaller.
